[June 12, Lopez de Lima has written a book on the statistics of San Thome' and Principe, in which he gives a short account of the natural history of the two islands ; but he never visited them. Erman received some skins of birds from Bissao and Principe from a Brazilian, and ran the risk of mentioning those from Bissao as having been collected in Principe, and vice versa. Their notes are therefore without value. 2. O n the Occurrence on the Coast of Cornwall of an Example of the Fish called Cuviers Ausonia or Luvaru.

R. T. Lowe, of an example, supposed to be of the same species, obtained in Madeira. The circumstances under which our example of this fish was met with in Cornwall appear to include a portion of its natural history, since something similar is related of one which formed the subject of Nardo's observations ; and as our specimen has been added to the collection in the British Museum, after it had incurred considerable risk of being lost to science, it may be of some interest to relate a portion of the particulars, the more especially as they will account for the injury which it received at the time of its capture, and which would have been greater but for the skill bestowed on its preservation by Mr. William Laughrin, A.L.S.
